Does anybody know anything about vintage Waterman #3s? I've not come across one before. Are they broad, fine, or (most importantly) flexy?

Thanks!

The Waterman 3 was one of their value line pens in the late 1930's. It was available in around 5 different colors, and also in a shorter, "vest pocket" V version (3V.)

From a page in the 1936 Pen Prophet:
"The No. 3 and No. 3V are especially suitable for boys and girls returning to School--and for the many adults who prefer a full size, moderately priced pen."

While this was one of Waterman's value pens, the 3 is very well made. Nibs are found on these in much the same (wide) spectrum as on other pens of the day (94, 92, Ink-Vue.)
The good news of this is that broad or flex nibs can definitely be found on 3's. The bad news is that there isn't a good way to "know" until you look closely or try the nib.

Thanks!

I have one. It is the flexiest writer I have ever used. This is one pen I just would never sell. The tip is not very smooth though except at the small sweet spot which is around 30 degrees to the vertical - my usual writing is 45 from paper. But, nevertheless, the pen adds a ton of character to even my shabby handwriting. I love it. You really should get one. (Mine is 1932 I guess.)

P.S.: It writes a Medium at normal pressure.
